The Conquerors Mark II used to have a health number. I'll assume their stats are same/similar.

Light Soldier is 100.

Heavy Soldier is 100

So they have same health. On the description it says it has more attack power. Which is probably true with The Conquerors 3 aswell

Someone test if its true or not. Test the stats. Not with command center but rather having a friend to use Light vs Light Light vs heavy etc. Alright I'll update the rest thanks bye
